A simple portable ultrasonic diagnostic apparatus can be realized.

  Hereinafter, an embodiment of an ultrasonic diagnostic apparatus according to the present invention will be described in detail with reference to FIGS.

  FIG. 1 is a system diagram showing a schematic configuration of an embodiment of an ultrasonic diagnostic apparatus according to the present invention. The ultrasonic diagnostic apparatus body 10 includes a transmission unit 11, a reception unit 12, a B mode unit 13, a Doppler unit 14, a DSC (digital scan converter) unit 15, an image memory 16, a panel information memory 17, a display selection control unit 18, and the like. A system control unit 19 having an arithmetic unit (CPU) and a memory for organically controlling these components, a display unit 20 and an operation unit 21 are further provided. An ultrasonic probe 30 responsible for transmitting and receiving ultrasonic signals to and from a person is connected.

  The ultrasonic probe 30 is driven by the transmission unit 11 of the ultrasonic diagnostic apparatus main body 10. That is, the transmission unit 11 includes a delay circuit and a pulser, generates a pulse signal at a constant transmission interval according to the rate pulse controlled by the system control unit 19, and supplies the pulse signal to the ultrasonic probe 30. A large number of piezoelectric elements provided at the tip of the ultrasonic probe 30 are sequentially driven by this pulse signal, and pulsed ultrasonic waves are sent to the subject so as to have a predetermined directivity. The transmitted ultrasonic wave is reflected by the discontinuous surface of the subject's acoustic impedance, and the reflected wave is received by the ultrasonic probe 30. The reflected wave received by the ultrasonic probe 30 is taken into the receiving unit 12 as an echo signal for each channel, amplified by a preamplifier in the receiving unit 12, and a delay necessary for determining the reception directivity by the reception delay circuit. Time is given and added by the adder circuit.

  Next, the output of the receiving unit 12 is introduced into the B mode unit 13. The B mode unit 13 is provided with a detection circuit, a logarithmic amplifier, and an A / D converter. The echo signal is detected to obtain an envelope, which is logarithmically amplified and then converted into a digital signal. This digital signal is a raster signal sequence of a tissue tomographic image and is sent to the DSC unit 15.

  On the other hand, the output of the receiving unit 12 is also introduced into the Doppler unit 14. The Doppler unit 14 includes a mixer, a low-pass filter, an A / D converter, an MTI filter, an autocorrelator, an arithmetic unit, etc., extracts a Doppler signal from an echo signal, and from among these, a fast moving body such as a blood cell In addition to extracting high-frequency components that have undergone a frequency shift due to reflection at the same time, low-frequency components (clutter components) that have undergone the frequency shift due to reflection by a slow moving body such as the heart wall are removed. Then, frequency analysis is performed on the Doppler signal including only the blood cell component to obtain a deviation frequency by the blood cell, and a blood flow image signal such as a blood flow velocity and a blood flow volume is obtained based on the frequency, and this signal is stored in the image memory 16. To do.

  The raster signal sequence of the tissue tomographic image from the B mode unit 13 is subjected to processing such as interpolation by the digital scan converter circuit of the DSC unit 15 and is converted into a raster signal sequence in a video format, that is, a TV scanning system, and further D / A The signal is converted into an analog video signal by a converter to create a B-mode image. Similarly, the blood flow image signal stored in the image memory 16 is also converted into a TV scanning signal by the DSC unit 15 to create a color flow image. Both images can be superimposed as necessary, or text information can be superimposed to form a video signal.

  The image memory 16 also stores B-mode images and color flow images created by the DSC unit 15 and can read them as past images as necessary.

  In the panel information memory 17, various function switches for two-dimensionally displaying a B-mode image to be displayed on the display screen 102A (touch command screen) of the second operation panel 102 in the conventional apparatus shown in FIG. The contents of the touch panel are stored, such as and buttons, and various function switches and buttons for displaying the color Doppler mode.

  These DSC unit 15, image memory 16 and panel information memory 17 are connected to a display selection control unit 18. The display selection control unit 18 is controlled by the system control device 19 based on instruction information from the operator input by the operation unit 21. The DSC unit 15, the image memory 16, and the panel information memory 17 to be displayed on the display unit 20. And the like are distributed to the display unit 20.

  Next, the display unit 20 will be described.

  The display unit 20 of the ultrasonic diagnostic apparatus according to the present invention includes a touch command screen based on an electrostatic coupling method that is formed on a front surface of a multiple view directional display 201 with a transparent material that does not interfere with the display of the multiple view directional display 201. 202 is bonded.

  For example, as disclosed in detail in Japanese Patent Application Laid-Open No. 2005-284592, the multiple-view directional display 201 is configured to observe different images from the left and right or up and down directions with a predetermined parallax angle, for example. This is a liquid crystal display device made possible. By applying such a multiple-view directional display 201 to the display unit 20 of the ultrasonic diagnostic apparatus, it has become possible to dramatically improve the diagnostic function of the ultrasonic diagnostic apparatus. To do. In order to simplify the description, a case will be described in which two images are displayed on the multiple view directional display 201 and they are observed from the left and right oblique directions.

<First use example>
FIG. 2 shows a case in which the B-mode image and the content of the touch panel are displayed on the display unit 20 so as to be observable as a first usage example of the ultrasonic diagnostic apparatus according to the present invention. That is, the display selection control unit 18 selects the B mode image (live image) obtained from the DSC unit, and the panel information indicating various function switches and buttons related to the B mode image from the panel information memory 17, These are processed so as to have a predetermined pixel distribution, and supplied to the multiple view directional display 201 as one image data. In this case, for example, an image A (B mode image) in which adjacent pixels of the multiple-view directional display 201 are viewed from the left diagonal direction (hereinafter simply referred to as the left) and a right diagonal direction (hereinafter simply referred to as the right) Driven) according to the data of the image B (contents of the touch panel) visually recognized. In other words, adjacent pixels are driven according to image data for different directions.

  Therefore, in the first usage example shown in FIG. 2, an operator such as a doctor who operates the ultrasonic diagnostic apparatus visually recognizes the display unit 20 from the left as indicated by an arrow L while operating the ultrasonic probe 30. Then, while observing the B-mode image (image A) of the subject, and when the operation of the screen is necessary, as shown by the arrow R, the line of sight is moved so that the display unit 20 is viewed from the right side, and the contents of the touch panel are displayed. While confirming (image B), touch a desired switch with a finger or a touch pen. Since the touch command screen 202 is pasted on the front surface of the display unit 20, that is, the front surface of the multiple view directional display 201, the position touched by the operator is detected by a touch position detection circuit (not shown), and the information is displayed and selected. The information is transmitted to the control unit 18 or the system control device 19 and a subsequent instruction is given.

  Thus, according to the first usage example, it is not necessary to equip the ultrasonic diagnostic apparatus main body with the second operation panel 102 as in the prior art, so that the ultrasonic diagnostic apparatus can be extremely miniaturized.

<Second usage example>
FIG. 3 shows, as a second example of use of the ultrasonic diagnostic apparatus according to the present invention, for example, a B-mode image (image A) and a color image (image) as two types of images subjected to different image processing on the display unit 20. B) is displayed so as to be observable. That is, the display selection control unit 18 selects a B-mode image obtained from the DSC unit and a color image obtained from the image memory 16 and processes them so as to obtain a predetermined pixel distribution, thereby obtaining one image data. To the multiple-view directional display 201, for example, a B-mode image (image A) can be visually recognized from the left side of the display unit 20, and if the line of sight is moved to the right side, a color image (image) B) can be visually recognized.

  The second usage example is not limited to displaying a B-mode image and a color image as two types of images subjected to different image processing, but a B-mode image and a B-mode image, and a B-mode image and a Doppler. A combination of an image, a color image and a Doppler image, a Doppler image and a Doppler image, or a combination of a live image and a past image, an image and a measurement screen, an image and a measurement result, and the like are appropriately selected by an operator. And display it.

  According to the second usage example, two different images are displayed on the entire screen of the display unit 20, and a sufficient display area can be secured. For example, when it is desired to observe the Doppler waveform, the operator determines whether or not the blood flow is firmly grasped, and the operator looks at both images displayed on the display unit 20 without switching the display mode. Since they can be compared and observed simply by moving them, extremely accurate diagnosis can be performed while reducing the burden on the operator.

  Conventionally, when two images are compared and observed, as shown in FIG. 7, the screen of one display unit is divided into two, and two small images are displayed side by side. Therefore, although it is not suitable for detailed diagnosis and there is a possibility that an important part is overlooked, such an inconvenience can be solved according to the present invention. Moreover, the troublesomeness of displaying two images by the switching operation can be eliminated.

  The display of the two images on the display unit 20 using the multiple view directional display 201 according to the present invention is not only for the operator, but the operator (doctor) explains the diagnosis status to the subject. It can be used conveniently when you want to. For example, if the operator (doctor) is sitting on the left side and the subject is sitting on the right side toward the display unit 20, the operator (doctor) can be viewed from the left side by displaying the same image as two images. If the diagnosis contents are explained while viewing the image to be viewed (image A), the subject can hear the explanation while viewing the same image as the right image (image B). Therefore, there is no inconvenience that the operator's (doctor) 's body or hand is in the way and the user cannot see the screen well, and the effect that the diagnostic result is surely understood can also be obtained.

<Third use example>
FIG. 4 shows a third example of use of the ultrasonic diagnostic apparatus according to the present invention, in which two types of images displayed on the display unit 20 so as to be observable from the left and right directions are fitted with a small image B in the image A. The image A is inserted into the image B in a small size and displayed. That is, for example, as shown in FIG. 3 as a second usage example, when the image viewed from the left side is a B-mode image (image A) and the image viewed from the right side is a color image (image B), In the third usage example, a small color image is fitted into the B-mode image as image A, and a small B-mode image is fitted into the color image so that it can be visually recognized as image B. It is.

  In this way, the operator can know what image is displayed as the image B without observing the image A, and the diagnosis can be made more appropriate.

<Application example of the present invention>
FIG. 5 shows, as an application example of the present invention, the state of the display unit 20 and the operator OP operating it. That is, the display unit 20 is attached to the upper end of the column 211 provided on the base 210. Since the display unit 20 is a liquid crystal display device and is lightweight, the display unit 20 may be a light pedestal 210 and a column 211 that are portable enough to support the display unit 20. The pedestal 210 is provided with a simple drive device (not shown), whereby the support column 211 can swing over a predetermined angle range. Moreover, the support | pillar 211 can be slid to the up-down direction only by the predetermined range, and is comprised so that the height of the display part 20 can be adjusted. Further, the pedestal 210 is provided with a switch 212 that can be switched by the foot of the operator OP.

  The operator OP, while sitting on the chair, displays a tomographic image of the diagnosis part of the subject on the display unit 20 while operating the ultrasonic probe 30 and observes it. For example, when the operator OP is currently observing the screen from the left side of the display unit 20, the front surface of the display unit 20 is at a position rotated to the right by the amount of parallax with respect to the operator OP. Therefore, when the switch 212 is stepped on with a foot, a driving device (not shown) provided on the pedestal 210 is driven, and the column 211 is rotated leftward by a predetermined angle. Accordingly, the display unit 20 moves to a position rotated to the left by the parallax angle with respect to the operator OP, and is positioned so that the operator OP can easily observe the screen from the right side of the display unit 20. When the operator OP steps on the switch 212 again, this time, the support column 211 is reversed rightward by a predetermined angle, and is positioned so that the operator OP can easily observe the screen from the left side of the display unit 20. become. The display unit 20 may be rotated instead of rotating the column 211 by the driving device.

  This application example is particularly useful when a B-mode image or the like is displayed as the image A on the display unit 20 and the contents of the touch panel are displayed as the image B as shown in FIG. It is. That is, when the operator OP holds the ultrasonic probe 30 in the left hand and displays the B-mode image of the diagnosis site of the subject on the display unit 20 as the image A and observes it, the contents of the touch panel are displayed as the image B. When the display is made, the operator OP rotates the display unit 20 to a necessary angle when performing various settings / adjustments for the image A, so the image A is observed from the image A to the image B without moving the line of sight. The object can be changed and the touch panel can be freely operated with the right hand. Therefore, the burden on the operator OP is greatly reduced, and it is possible to concentrate on the diagnosis.

  As described above in detail, according to the embodiment of the present invention, it is possible to display a plurality of images without changing the display size on one screen, and an operator such as a doctor simply shifts the parallax. Multiple images can be observed. Therefore, diagnosis while comparing a plurality of images is facilitated, and improvement in diagnosis accuracy is expected while reducing the burden on an operator such as a doctor. Furthermore, an ultrasonic diagnostic apparatus having great features such that various usages can be selected as necessary for the purpose of diagnosis and the like can be miniaturized.

  Needless to say, the present invention is not limited to the above-described embodiments, and can be implemented in various forms without departing from the scope of the invention. For example, the display unit 20 does not necessarily have to be attached to the ultrasonic diagnostic apparatus main body 10 or provided on the pedestal 210 via the support column 211, and is connected to the ultrasonic diagnostic apparatus main body 10 with a cable. The operator OP may be held in the hand that does not have the ultrasonic probe 30 to adjust the angle at which the display unit 20 can be viewed by moving the operator OP itself so that the images A and B can be observed. good.

  In addition, by providing the display unit 20 having the multiple view directional display 201 as a main body with all the functions as the ultrasonic diagnostic apparatus main body 10, it is possible to connect the ultrasonic probe 30 thereto. It is also possible to use an ultrasonic diagnostic apparatus. That is, all the electronic devices for obtaining an ultrasound image corresponding to the ultrasound diagnostic apparatus main body 10 are housed in a portable housing, and a multiple view is provided as a display unit 20 that displays the ultrasound image on the surface of the housing. A directional display 201 is installed. Then, if an ultrasonic probe that transmits and receives ultrasonic waves to and from the subject is connected to the housing, the operator OP has the ultrasonic probe 30 in one hand and the multiple view directional display 201 in the other hand. A portable ultrasonic diagnostic apparatus capable of carrying out ultrasonic diagnosis with an installed housing can be realized.

  Furthermore, as an example of the present invention, the case where two screens of the image A and the image B are displayed on the multiple view directional display 201 of the display unit 20 has been described. It can also be displayed.
